Hotfix 0.30.0a Patch Notes

Cosmoteer: Starship Architect & Commander · published 4 Aug 2025, 23:12 UTC · build 19486787

All newsPlayers around this dateRead on Steam

This is a small patch to fix a handful of issues in the recent "Meltdown Update".

  • The Thermal Resonance Lance's heat blast on destruction is now scaled by how much heat is in its storage.

  • Ammo Factories and H.E. Factories now have a chance of starting fires when destroyed.

  • Factory production animations now get faster when the factory has a speed buff.

  • Toggling off the U.I. (default Ctrl+Shift+U) will now hide fire icons.

  • Bugfix: Ships were surrendering when not intended.

  • Bugfix: The "Hull Heat" tutorial could constantly blink on-and-off. (It will now stay permanently once triggered.)

  • Bugfix: Overclocked Ion Beam Emitters were missing their firing sound effects and glow.

  • Bugfix: The description for the Thermal Canister Missile Factory incorrectly stated that it uses iron and sulfur. It has been corrected to copper and sulfur. (Note: Translations are not corrected yet.)

  • Bugfix: The Lance Dilation Pump's "Thermal Dilation" stat was erroneously listed as "Thermal Amplification".

  • Modding: Fixed the error "Polygons must have at least 3 vertices" with polygon colliders that don't cover all cells or are counter-clockwise.
